gbhrps Posted January 30, 2018 Share Posted January 30, 2018 Ladies and gentlemen. I've been running my winter tire and steel wheel setup, which has no valve stem TPMS transmitters. So why do I not have the TPMS light on the dash lit up to tell me I have an issue? Every subie I've previously owned, that had a TPMS system, would light up all winter long, until I reinstalled my factory summer tires and wheels in the spring. Has Subaru changed the system on this 2017 OBW Premier with Eyesight and the Tech Package? Quote Link to comment Share on other sites More sharing options...
golucky66 Posted January 30, 2018 Share Posted January 30, 2018 Very possible it uses the ABS system to determine speed difference in each tire, and calculates the tire pressure with that speed difference. Not 100% that they don't have sensor though Quote Link to comment Share on other sites More sharing options...
matt167 Posted January 30, 2018 Share Posted January 30, 2018 If it uses the ABS/ CAN bus system then there will be a reset button somewhere. Have not touched a '17 yet Quote Link to comment Share on other sites More sharing options...
gbhrps Posted January 31, 2018 Author Share Posted January 31, 2018 Gentlemen, I guess I'll have to wait until the spring when I install the factory mags and tires. If I don't see a dash TPMS light at start up, I'll stop into a subie dealership and see what they have to say. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted January 31, 2018 Share Posted January 31, 2018 If the lights not on don't complain! Those things are nothing but an annoyance anyway. If the light comes on its because the tires were already about 7psi low and have been low on pressure for a LONG time before the light ever came on. Damage to the environment and your wallet already done at that point. 1 Quote Link to comment Share on other sites More sharing options...
